Abstract :
This paper proposes a novel method to generate a sinusoidal waveform for synthesizing a sinusoidal reference current in certain applications of parallel active power filters. The method, based on the behavior of a three-dimensional dynamical system, avoids employing the usual combination of look up table and PLL found in most parallel active filters synthesizing a sinusoidal source current. The method produces two high-quality sinusoidal waveforms in quadrature, applicable to those parallel active filters whose control methodology is in the α/β frame, or alternatively, three sinusoidal waveforms shifted 120 degrees from each other for designs that work in the abc frame.
